Abstract: ABSTRACT OF THE DISCLOSURE           A process for the pressure oxidation leaching of non-ferrous metal sulphidic material which comprises provid-ing an autoclave assembly which has a series of successive compartments, the first compartment of which being substan-tially larger in size than each of the remaining compartments.          An oxygen partial pressure is provided in the autoclave as-sembly in the range of from about 50 to about 2000 kPa.  An aqueous slurry of the material is fed into the relatively large first compartment with resultant flow of the material through the successive smaller compartments causing the tem-perature in the first and successive compartments to be suffi-cient to produce autogeneous oxidation of the sulphidic material.  The oxidized slurry from the last compartment of the series is discharged.

Abstract: ABSTRACT    In a process and a fluidised bed reactor for the gasification of carbonaceous substances, exothermic and endothermic gasification agents are injected into the reaction area through at least one nozzle comprising at least two coaxial pipes, the outer pipe terminat-ing short of the end of the inner pipe, at a distance such that the end face of the outer pipe is in a region of the pressurised interior of the reactor, in which the temperature is below the melting point of the ash of the solid particles to be gasified. The speed of flow of the endothermic agent out of the annular gap between the pipes is substantially higher than the speed of flow of the exothermic agent out of the inner pipe and the flow of endothermic gasification agent tends to be constricted around the flow from the inner pipe. The outer edge of the inner pipe is a sharp, right-angled edge so that in the region thereof eddies are formed which protect the region from the penetration of particles of ash therein.

Abstract: ABSTRACT OF THE DISCLOSURE     A universal joint of the type utilizing spherical roller balls to transmit torque or power between an inner joint member and an outer joint member.  The balls roll in a recess in the inner joint member and each ball rolls in a rectilinear recess in the outer joint member, with such rolling action permitting and resulting from the articulation of the joint.  Each recess in the outer joint member has at least a major portion that has a radial extent, from the central axis of the joint, that follows a cur-vilinear configuration to provide a maximum radial extent when the inner and outer joint members are aligned, through a gradually reducing radial extent as the joint is articulated, in order to provide a substantial constant depth of penetration of each-ball into its outer joint member recess throughout the range of articulation of the joint.  This helps to maintain the elements of the joint in contact with one another over a relatively wide range of joint articulation, to maintain free-play transmission of torque between the inner joint member and the outer joint member over this range of articulation.  The joint also has complemental spherical surfaces on abutting portions of the inner and outer joint members to permit them to articulate in an axis at right angles to the axis of articulation through the outer joint recesses and to sustain end or compressive loads applied to the inner and outer joint members.  The joint has particular utility as a two-ball joint in an automotive tilt-steering system.

The starting scoring is part of a field of a plurality of scorings formed on the tear-off strip below the tongue. The welding zone partially covers over this field. As a result, care is taken to ensure that a tearing open operation can be reliably initiated by rolling up the tongue, substantially regardless of inaccuracies in manufacture.
